A preamplifier (preamp) is an electronic amplifier which precedes another amplifier to prepare an electronic signal for further amplification or processing. Description In general, the function of a preamp is to amplify a low level signal (possibly at high impedance) to line-level. A list of common sources would include a pickup, microphone, turntable or other transducer. Equalization and tone control may also be applied. In a home audio system, the term 'preamplifier' may sometimes be used to describe equipment which merely switches between different line level sources and applies a volume control, so that no actual amplification may be involved. In an audio system the second amplifier is typically a power amplifier (power amp). The preamplifier provides voltage gain (about: 10millivolts to 1volt) but no significant current gain. The power amplifier provides the higher current necessary to drive loudspeakers. Preamplifiers may be: •incorporated into the housing or chassis of the amplifier they feed
•in a separate housing
•mounted in other pieces of equipment, such as turntables, microphones and electric basses.
•close to the signal source, remote from the next amplifier -- eg: beside hi-fi system, then feeding into a computer in the home office. Examples •the integrated preamplifier in a foil electret microphone.
•the first stages of an instrument amplifier.
•a stand-alone unit for use in live music and recording studio applications.
•as part of a stand-alone channel strip or channel strip built into an audio mixing desk.
•a masthead amplifier used with television receiver antenna or a satellite receiver dish. http://www.answers.com/preamplifier?cat=technology
A preamp A preamp.
There are many places online to buy a preamp. Amazon sell a range of preamp products including ultra compact preamps. The site Preamp also stocks a wide range of preamps.
To test the output of an acoustic guitar preamp you may use output tubes to test. This will test the preamp voltage.
Yes it is just a preamp you need an audio interface that will connect the preamp to the audio interface into the computer and obviously a Mic in front of it
Components are parts of a whole. For instance, a preamp is a stereo component, and a stereo consists of a turntable, a preamp, an amp, and speakers.
A microphone preamp is a preamplifier used to amplify a microphone's low output voltage to a stronger, more usable level. A microphone preamp must provide stable gain for small signals without being sensitive to induced noise from cabling and without distorting large amplitude signals. Most microphones must be used in conjunction with a microphone preamp to function properly. The microphone preamp has been called mike preamp and mic preamp; this has been shortened further to mic pre and, in settings where a distinction is not necessary, simply pre.
NO preamp has wattage or a wattage rating. The only wattage involved in a sound system comes from the POWER amp
A preamp can be used to change the tones of certain instruments. There are several online music stores where you can find them at, and some websites will hlep you build one yourself.
You need a power amplifier in between.
